Method for preparing graphene thermal conductive pad and use thereof

A method for preparing a graphene thermal conductive pad, comprising the following steps:

• S10, providing a plurality of graphene foam sheets;
• S20, removing surface crusts from the plurality of graphene foam sheets, performing laser perforation and edge trimming, and plasma activation to obtain activated graphene foam sheets;
• subjecting the activated graphene foam sheets to a first modification treatment with hydroxyvinyl silicone oil to obtain a plurality of first graphene foam sheets;
• S30, subjecting the plurality of first graphene foam sheets to a second modification treatment with an adhesive to obtain a plurality of second graphene foam sheets;
• S40, bonding the plurality of second graphene foam sheets along a thickness direction and pressing into a block, followed by curing, to obtain a third graphene foam sheet;
• and
• S50, slicing the third graphene foam sheet along the thickness direction to obtain a graphene thermal conductive pad;
• wherein the adhesive comprises linear low molecular weight vinyl silicone oil, linear medium molecular weight vinyl silicone oil, linear high molecular weight vinyl silicone oil, a crosslinking agent, a chain extender, a reinforcing agent, a toughening agent, a catalyst, and an inhibitor.
